Covered this in 6 minutes My teacher couldn’t explain this in a week

It's quite fun to just surf through your lessons, cry at the complexity of half of the teacher explanations, and then come here and listen to you cover it simply in, like, 5 minutes or so. It's really helpful. :D

I don't find these "long" videos boring, these are exciting and I am all for it. if cognito's video were long then a movie must look like an eternity.

Didn't feel too long, excellent, really well explained. Thank you.

Anyone else her because they didn’t understand what their teachers said but this video explained it clearly in 6 minutes 🙋‍♀️

Online schoolwork because of coronavirus squad? 2021 update - year 11 and given up on good grades lmao

you helped me so much man. i went from a 6 6 7 in my first combined science mock to 8 8 9 in my most recent mock. ive got my final set of mocks before gcse starting on monday

I love that your videos have mini diagrams, being a visual learner with a photographic memory allows me to absorb information better and easier. Thank you!

Hi! This video was definitely not too long, I found it was the perfect length to consolidate and take further notes during home learning.

This video is class . Thanks for helping me revise.

It's not long, it's perfect - because the structure, content and animation was exceptionally planned ❤

This is a brilliant video; with its great animations and flow diagrams. It really has helped my understanding of the process. Thank you so much!

awesome vid. straight to the point and comprehensive. it can even be shown at separate stages. pls do more topics like this

Thank you for that video it was very informative and straight to the point and has helped me alot with this subject, Keep up the good work 👏 🙌

This length of videos is amazing and fits well with the way I take notes. Also, I just want to say thank you for these amazing videos that have, quite frankly, saved my life. God Bless.

longer videos are actually really nice. Thank you :)

Great explanation but you missed the main reason why placebos are used- because of the placebo effect, when the patient expects to feel better and their brain is tricked into thinking the symptoms have been treated even though they haven't, so they feel better anyway. Placebos are used so you can see the actual effect of the drug rather than just the placebo effect

Great video, really helps with revising and covers just the right amount of relevant info for exams

great video!! i have my biology mock tomorrow and these videos are really helping with revision :) UPDATE: i actually think i did really well, although i don't want to jinx it just yet!!!

the more longer videos and the more detail and info the better! thank you for this video :)

this was really helpful! i love the longer videos since it's explained even better :)

Thank you cognito, I went from a 4-5 in my first science mock to a 7-6 by my second because of your videos!

another great video!!! you’re helping so many people right now!!

thanks Mr.cognito ur the reason why i am going to pass my science exams :)

These ‘longer’ videos are not long and are amazingly amazing

Thank you, this was really helpful!!

No it’s not too long it is perfect and well explained!

I believe that the length of the video was very appropriate for the topic that you were covering. Thank you for helping GCSE students getting a high grade. PS. will you have chemistry as a subject as well?

the long videos are actually good!

Why can’t you be my real teacher😂

A very good video, thank you for your effort making them!

COGNITO VIDEOS AND THEIR WEBSITE R SUPERIOR😍 thanks amadeus and tom :)

I really appreciate this 😭😭thank you

Nice💯 No problem with the length of the videos at all

Long videos are fine as long as they are under 8-10 minutes. I like the videos that you post because they cover big topics within 4 to 6 minutes.

Thank you I literally have a test tomorrow about this topic

Thank you very much, Cognito!

thank you this was so useful!!

Can these video series be relied completely to attempt CIE next week?

watching the video in 2x speed so I finish it in 3:13, modern problems require modern solutions.

thank you, this is also a topic in a level biology, so this was quite helpful.
